Title: Projection aligner
Inventor: MIYAI TSUNEO
IPC: H01L21/027
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To carry out exposure on a whole exposure area on a photosensitive substrate with mask patterns always being best focused even if the mask is warped by its weight or by heat. SOLUTION: An image of opening patterns provided on a reference substrate 1 is projected onto the pattern surface of a mask 3 through a projection optical system. Its reflected image is projected again onto the reference substrate 1 through the projection optical system. The amount of received light of a detector 7 is detected in multiple positions with shifting a substrate stage 12 to detect the image forming surface of the patterns of the mask 3. A control system 10 controls a substrate placing surface shape driving system 16, so that the shape of the substrate placing surface of the substrate stage 12 may correspond to the image forming surface of the mask patterns.

Title: Starting circuit for microprocessor
Inventor: INOUE AKIRA
IPC: G06F9/06
Filed: 1987-09-30
Abstract: PURPOSE:To start execution of a program at an optional address by securing such a constitution where a no-function instruction generating circuit delivers a no-function instruction to the data bus of a microprocessor and feeds idle the program start address to a desired address from an address 0 after an initial resetting action when a flip-flop FF detects an initial reset signal. CONSTITUTION:A no-function instruction generating circuit 17 gives the no- function instructions to data buses DB0-DB7 after application of a power supply. Thus a microprocessor 11 carries out these no-function instructions repetitively. When the values of address buses AD0-AD15 reach each desired address, an output terminal Y3 of an address decoder 14 is set at an H state and therefore an instruction read control signal is supplied to an instruction read control terminal 18. Then a flip-flop FF5 is set by the output of an AND circuit 19 and the output of an output terminal Q is set at an H state. At the same time, the circuit 17 becomes floating and the inhibited state is released for AND circuits 150-153. Therefore the execution of programs are started on a memory at and after the addresses delivered from memory selection terminals 160-163.

The ring-shaped space 5 located on the side of the inner periphery of the outer pipe 4, together with its pressure-resisting strength which may be required under vacuum conditions, it not held by the side of the outer pipe 4 but by the bendable laminated body 6, so that the outer pipe 4 can easily be reduced in its wall thickness and also in diameter. An organism freezing probe 10 can thus be obtained which is in the form of a long and narrow pipe and capable of being integrated into an endoscope.

Title: Method and apparatus for mixing synthetic resin with glass fibre
Inventor: ORIMO YASUJI
IPC: B29C48/03
Filed: 1983-12-29
Abstract: PURPOSE:To render the kneading of a resin in a melted state and glass fibres smooth, by charging the melted resin and the glass fibres into a screw extruder with the charging positions and the charging timings differentiated. CONSTITUTION:First, a melted resin 6a is charged via a hopper section 12 toward a screw 9. Second, glass fibres 8 are charged downstream of the position where the melted resin drops from a metering feeder via a chute 15 to the screw 9 so that the position of the charging of the glass fibres 8 is away from the melted resin. Thus as the charging positions and the charging timings of the melted resin and the glass fibres are differentiated, the melted resin 6a is first located at the pressing side C1 of the screw 9 and after it is rolled around the screw in the course of the rotation, since at the feeding position of the glass fibres 8 there will be formed a space at a non-pressing side C2 of the screw 9, the glass fibres 8 are fed to fill the space thereby the glass fibres are evenly mixed without being damaged.

Title: Read-only semiconductor storage device
Inventor: AKASHI TSUTOMU
IPC: H01L29/73
Filed: 1988-09-29
Abstract: PURPOSE:To decrease a value of write current for preventing deterioration of a collector-base junction in a memory cell after a writing process while improving writing yield by decreasing a size of an emitter of the memory cell and increasing density of write current to the length of circumference of the emitter. CONSTITUTION:Length of circumference of an emitter electrode 7 of a memory cell is reduced to about a half of that of ordinary ones and write current is also reduced to about a half. Thereby, an alloy spike created during a writing process becomes very small and the tip of such alloy spike 8 will be present in a base region 5 at a depth from the bottom of an emitter region 6 smaller than a half of the total depth of the base region 5, the base and emitter regions being demarcated by the emitter-base junction and the base-collector junction. Accordingly, there is very low possibility of the tip of the alloy spike reaching the collector-base junction. Therefore, deterioration of the collectorbase junction during the writing process can be prevented and writing yield can be improved.
